` I Application filed April 5, 1894. Serial No. 506,498. (No model.) i

To all wiwi/n, it may concern.-

VBe it.known that I, FREDERICI; S. GARRI- sON, a citizen of the UnitedVStates, residing in the county of Green (Argyle lP. O.) and State ofVisconsin, have -invented a new and useful Corn-Harvester, of which thefollowing is a specification.

The invention has special reference to an improvement in that class ofcorn'cutters wherein the corn is first out, and subsequently bundled.and deposited on the ground in a complete shock; and the invention hasfor its object to provide certain improvements in the derrick mechanism,by which the corn is shocked and deposited on the ground.

' A further object of the invention is to improve on the drivingmechanism for the carrier-chain.

A still further obj ect is to produce a shocker which will allow thecorn to be bound around it, and which will be capable of elevating itand finally dropping it on the ends and in a vertical position in thefield. I

To these several en ds my invention consists of certain improvedfeatures of construc` tion and combination and arrangement of parts thatwill be more fully described hereinafter and finally embodied in. theclaims.

In the accompanying drawings-Figure 1 represents a side elevation of mycomplete machine; Fig. 2, a front elevation; Fig. 3, a horizontalsection, taken justbelow the tableV of the machine; Fig. 4, a verticalsection through the derrick; Fig. 5, a detail sectional View of thecutting apparatus; Fig. 6, asimilar View of the shock former; Fig. 7,adetail view of the gearing for driving the carrier and cuttingapparatus; Fig. 8, a view of a modified form of draft apparatus; Fig. 9,a detail view of the gearing for winding the d rum mechanism; Fig. 10, aView of the clutch for actuating the gearing of the table; Fig. 11, adetail of the bearings for the carrier shafts; Fig. 12, a detail of thecarrying-chain.

The frame of the machine Vconsists of two longitudinal beams 1, joined.to each other, and the whole made rigid'by Ithe cross beams or braces2, 3, Il and 5, which beams are joined to the beams 1 by any suitablemeans, preferably by the lugs 6, projecting inwardly from the beams 1,and havingthe cross-beams bolted thereto. Arising from the beams 1.

are the standards or posts 7, which are four in number, two for eachbeam 1, and which are rigidly 'secured to the longitudinal top-v beams8. These beams 8 are one for each pair of standards 7, and extendparallel with the beams 1.

Secured to the forward ends of the beams 8, which ends project slightlybeyond the front standards 7, is the cross-beam 9. This beam 9 isrigidly secured to the beams 8, and

provided with the seat 10, upon which the upwardly and thence forwardly,so that the forward portion will lie a distance above the main part ofthe beam 1, and it is in this raised or elevated portion, numbered 16,that the spindle 14 is journaled. By this meansit is possible to makethe wheels 11 larger than would otherwise be possible, and consequentlyincrease their strength and the ease with which the machine may bedrawn. The wheels 12 are fixed to the rear and driving axle 17, so as torevolve therewith, and'this is revolubly journaled in the rear ends ofthe beams l.

I will now describe the cuttingapparatus and the means provided foroperating the same. Secured to the beams 1, at a pointjust `rearward ofthe raised ends 16, is the transverse bar 18, which is arranged in thenotches 22 of the beams 1, and which extends from one beam to anotherand is provided with the stationary cutting teeth 19. These teeth aresubstantially triangular in shape, and are bolted to the bar 18 by meansof the bolts 20, countersunk in the face of the teeth, so as to lieIiush with their upper" face, andthe teeth are arranged with their rearedges in transverse alignment, so that their remaining edges will fo'rmV-shaped or daring recesses, into which the corn is adapted to passprior to severance.

The upper and reciprocating knife or cutter bar consists of a transversebar 21, which IOS) lies in the notches 22 in rear of the bar 18. Securedto the under side of the bar 18, and projecting rearwardly and upwardlyso as to embrace the bar 21, are the arms 23, which are provided to holdthe bar 2l in place and to allow it free reciprocal movement. The upperface of the bar 21 lies slightly above the upper face of the bar 18, andin the same horizontal plane as the upper surface of teeth 1o 19, sothat the cutter-teeth 24 will project out forwardly and lie in closeengagement with the teeth 19. rlhe teeth 24 and 19 are of the same size,and the cutting-edge of the former are beveled from the upper face downand out r 5 wardly to the lower face, thus placing the plain upper facesof teeth 19 and the plane lower faees'of teeth 24 adjacent, and, by sodoing, making the appliance cut with greater ease and speed.

livotally connected to one end of the bar 21, and extending laterallytherefrom, is the link 25, which is connected at its outer end to thecrank-pin 26, of the disk 27, and the disk 27 is, in turn, fixed to thelongitudinallyextending shaft 28. The shaft 28 is arranged on theoutside of and parallel with the adjacent beam l, and is revolublymounted in the boxes 29, which are fixed to said beam. Fixed to the rearend of the shaft 28, beyond its 3o bearings,is the beveled gear 30,which meshes with the corresponding gear 3l, and this is, in turn, fixedto the outer end of the trans- Versely-extending shaft 32. Shaft 32 isjournaled in the side beam 1, and projects in- 3 5 wardly therefrom fora short distance, and

for a purpose that will hereinafter appear.

Fixed to the shaft 32, and lying flush with gear 3l, is the pinion-gear33, which is adapted to mesh with the internal cog-rim 34 of the 4oadjacent carrying and driving wheel l2. The wheel 12 serves to impart acontinuous rotary movement to the shaft 23, said movement beingtransmitted, through the medium of gears 31 and 30, to the shaft 28,thence to disk 27, and finally to link 25, and cutter-bar 21, re-

sulting in a reciprocation of said bar, which eo-operates with thecutter-bar 18.

The carrier mechanism consists, essentially, of four rearwardly-inclinedshafts 35, 36, 37 5o and 38, which are all journaled at their upper endsin bearings 43, in the transverse bars 39, said bars 39 being secured,respectively, to the front ends of the beams 8, and projecting inwardlyfrom the same toward each other. The shafts 35 and 36 are journaled inone bar 39, while shafts 37 and 38 are journaled in the other bar 39.The lower ends of the shafts and 38, or the outer shafts, are journaledin the inclined bearings 40, formed one in 6o each beam 1, and a shortdistance to the rear of the cutting apparatus, while the inner Ishafts,or the shafts 36 and 37, are journaled respectively in bearings in theplates 4l, secured near the center of the beam 2, and projectingupwardly and forwardly therefrom.

Fixed to the shafts 35 and 38, are the sprocketwvheels 42, there beingthree foreach shaft, and over the saine operate the sprocketchains 44.From the wheels 42 the chains44 pass to the sprocket wheels 45 of theshafts 36 and 37, three of the wheels 45 being fixed to each of saidshafts. The inner shafts 36 and 37 are rotated to cause the frontportions of the chains 44 to move toward each other, or inwardly, bymeans of shafts 45, 46, and 32 and attached gears.

The shaft 45 extends transversely and is journaled in the beams 1,justbelow the shafts 35 and 38, and is provided with the gears 47, 48 and49. rlhe gear 47 meshes with a gear 50, which is fixed to the lowerextremity of the shaft 37, below the plate 4l in which shaft 37 isjournaled; and the gear 48 on the shaft 45 meshes with a gear 5l, on theshaft 36.

Fixed to one extremity of the shaft 45, adjacent to one of the beams 1,is a beveled gear 52, which meshes with a gear 53, fixed to alongitudinal shaft 46, journaled in the beams 2 and 5. The rear end ofthe shaft 46 is provided with a gear 54, which meshes with a beveledgear 55, fixed, in its turn, to the adjacent extremity of the shaft 32.By this means the motion of the shaft 32 is transmitted to the shaft 46,and thence to the shaft 45, which will result in a revolution of shafts36 and 37, and, owing to"`ehains 44, a similar movement of the shafts 35and 38 or the outside shafts.

57 indicates a plate, which is fixed to the beams l, in rear of the bar2l, and flush with the upper faces of the knives 24, and from this pointthe plate extends rearwardly to the chains 44, and slightly past them,whereby the corn is given a smooth and unobstructed path to the chains.Between the shafts 36 and 37 the plate 57 extends rearwardly over theshaft 45L to the front edge of the platform of the machine, againstwhich it abuts.

rlhe carrier chains are provided withspurs 0r teeth 58, which arerigidly fixed to, or formed integral with, the links thereof.' Thesespurs 58 are preferably two for each link, though this may be varied atwill, and are adapted to engage the corn which is thrown against them,and carry it toward the space between the shafts 36 and 37.

In order to throw the cut corn against the carrier chains 44, I providethe reel 59, which consists of a transverse shaft provided with the armsor wings 60, and journaled in the front extremities of beams 61., whichare removably secured to the beams 8, and project forwardly and upwardlytherefrom to a point in vertical alignment with the cutting apparatus.It will be necessary to make the reel capable of adjustment in avertical line, so as to compensate for the difference in the height ofthe corn, and this is effected by the standards 62, which are fixed tothe forward extremity of the beams 8, and are provided IOC) IIO

with the vertical series of transverse holes 63, through which the bolts(i4 are adapted to pass. The bolts 64 pass through the beams 61, andengage the desired openings of said eaetfr s standards so that byraising and lowering the bolts the reel may be correspondingly adjusted.The reel is driven by the sprocketwheels 79 and 80, over which the chain81 operates to transmit power from one to another, the wheel 79 beingfixed to the shaft 45, while wheel 8O is fixed to the reel-shaft 59a.

indicates the machine platform, which is to be constructed, bypreference, of a wrought-iron framework, covered with galvanizedsheet-iron, and the platform extends forwardly from the rear axle of themachine .to the rear edge of the plate 57, as before indicated. Formedin thecenter of the platform 65, is the circular opening 66, in which arotary table 67 is arranged. This table is provided with a verticalspindle 68, which is revolubly seated at its lower end in the cupbearing69, of the beam 4. The table 67 is arranged with its upper face flushwith the platform 65, and is held from .vibration by the carryingwheels70, and the driving-gear 71. Wheels 70 are arranged two on the beam 4and one on the beam 5, and all are located in the depressions 72 of saidbeams, their axles 73 being disposed horizontally, while the wheelsthemselves are beveled slightly inwardly and adapted to mesh with thecogrim 74, which is xed to or formed integralI with the under side ofthe table 67. The driving-gear 7l is fixed to the rear extremity of ashaft 75, and lies ush with the rear edge of the beam 3, the shaft 75being jour-V naled in the box 76.of the beam 3 and projecting forwardlytherefrom to the beam 2, beyond which, after extending through thedepression 77 of the beam, it is provided with the beveled gear 78,which meshes with the gear 49 of the shaft 45t. The gear 78 is mountedon the shaft 75, so as to be capable of al limited longitudinalmovement, and this' is effected by the longitudinal rib or key 82 whichis fixed to, or formed integralwith, the front end of the shaft, andoperates in a corresponding slot or keyway in the gear 78. Thus the gearis capable of longitudinal movement on the shaft75, so as to engage ordisengage the gear 49. This movementof the gear 78 is effected by meansof the grooved sleeve 83, formed integral with the gear and projectingrearwardly therefrom; and the lever 84, which is provided at its lowerend with the forked arms 85, fitting in the groove of sleeve 83. Fromthe fork 85 the lever extends upwardly and through the opening 86 in theplatform 65, above which it is bent laterallyand is fulcrumed to thevertical pin 87, which arises from the platform 65.

88 indicates a plate rigidly xed to the platform 65, and risingvertically therefrom, and formed in the upper edge of this plate are thetwo notches 89, which are located one at each end of theplate, and havetheir inner sides inclined or curved toward each other. The lever 84 isadapted to engage one or the other of the notches 89, whereby it may beheld in position. By these means the operator may cause the gears 78 and49 to be engaged or disengaged, and may lock the parts in eitherposition.

The mechanism for shocking, elevating, and depositing the corn isconstructed as follows: Two vertical revoluble shafts 90 are mounted attheir lower ends in bearings in the beam 3, respectively, in rear of theshafts 36 and 37, and extend to and are mounted at their upper ends inthe beams 39. These shafts 90 serve to brace the `beams 39. Arranged onthe shafts 90, and capable of a vertical movement thereon, are thecollars 91, provided with set-screws 92, whereby they may be secured atany point along the length ofthe shafts. Rigidly secured to, or formedintegral with, the collars 91 are the radial arms 93. The ends of thearms on the lefthand shaft 90 being bent to the left, so that they willbe in position to project slightly to the left of the shaft 37, andnearly in transverse alignment therewith, (thus catching the corn as itpasses rearwardly from the carrier chains of the shafts 37 and 38,) andthe ends of thearms on the right-hand shaft 90 being bent to the rightso that they will be capable of operating similarly. .lhus, as the cornis-cut and carried to the center, it is caught,part by the arms of'eachshaft 90, and held so until the space between the arm 93, which isdirectly in the path lof the corn, and the arms on the outside thereof,is lled, whereupon an attendant may revolve the shafts 90, so as toplace the next arm 93 in position to catch the incoming corn; and sothat that already embraced by the first arm may be removed and placed onthe table 67.

Formed in the upper end of the right-hand arm 90, is a socket 94, forthe reception of the rotatable spindle 95, and secured to the spindle95, is the slidably adjustable collar 96, provided with a set-screw 159,whereby it may be locked at the desired adjustment. Rigidly fixed to orformed integral with collar 96, is the arm 97, which projects laterallyfrom the spindle 95, and is formed with the upwardly-extending lugs 98.On .the arm 97 the reins for controlling the team are adapted to beplaced, and by means of the lugs 98 the reins are prevented from fallingoff the arm during the driving of the team. The arm 97 should bearranged, approximately, in longitudinal alignment with the seat 10, sothat ,they will properly hold. the reins, and the mountings of spindleshould be such that the shaft 90 below it will be allowed free movementindependent of the spindle, since this must remain stationary.

Journaled in bearings in the right-hand 4beams l and 8, is the verticalelevator or derrick-mast 99, which projects a distance above the beam 8`about equal to the distance of beam 8 from the ground, the lower 'end ofthis mast being seated in the cup-beariug 100 of the beam l. The lowerportion of the mast 99 is rounded and reduced in size, and the reducedportion is embraced by the hollow shaft 101,

IIO

which ts snugly thereon, and passes down through the bearing in the beam8 to the upper surface of the beam 1. The mast 99 and shaft 101, arecapable of independent rotary movement, and the latter, shaft 101, isprovided at its lower end with the beveled gear 102, which meshes withthe cog-rim 103, of the right-hand carrying and drive wheel 12, wherebythe shaft 101 is revolved continuously, and imparts movement to thebeveled gear 104, which is fixed to its upper extremity' directly underthe main portion of the mast 99. From the gear 104 the motion of shaft101 is transmitted to the beveled gear 105, fixed to the lower end ofshaft 106, which is journaled in the box 107, just above the beam 8, andin the extended lower end of the jib 108, of the mast.

165 indicates a brace, which extends from the jib 108 to au intermediatepoint of the mast 99, and serves to brace and render rigid,

the former, a counter brace 166 being provided and extended horizontallyfrom the brace 165 to the mast.

To the upper end oi' the shaft 106, above the jib 108, is fixed thebeveled gear 160 which meshes with the beveled gear 109, of the shaft110. Shaft 110 extends along the upper side of the jib 108, and isjournaled in the upper end of the mast 99, and in the box 111, fixed tothe outer end of the jib, and the shaft projects out beyond said end ofthe jib for a distance suilicient to ad mit the mounting of the windingdrum 112 thereon. The drum 112 is slidably and rotatably mounted on theshaft 110, the longitudinal movement on its shaft being limited by thepin 113, on the outer extremityof the jib,and by the stationary clutchmember 114. This movement of the drum 112 is elfected by the rod 115 andcrank-shaft 116, the former of which is provided with a loop 117,adapted to lie in the annular groove 118, at the outer end of the drum,and which extends inwardly parallel with and above the shaft 110, to theupper extremity of the mast 99, and is slidably fitted in the eye 119,fixed to the block 111. Thecrank-shaft 116 is mounted in a bearing 120,arranged near the upper end of the mast. Attached to the lower end ofsaid shaft is a lever 121, so that by swinging the lever 121 the shaft116 will be turned and the rod 115 moved longitudinally to engage ordisengage the clutch mechanism of drum 112 by reason of the crank at theupper end of the shaft 116 to which rod 115 is connected.

To hold the lever 121 in the proper position I providethe segment 122,secured to the mast adjacent to the plane of movement of the lever, andthe pawl 123 on said lever to engage the teeth of the segment. Theclutch member 114 is xed to the shaft 110, so as to revolve therewith,and is provided with the serrated or notched face 124, which is adaptedto mesh with the corresponding face 125, of the drum 112, so that bymoving the drum on the shaft 110 it may be engaged with theclutch-member 114, and caused to revolve therewith, thus winding thecable 143 upon the drum. The cable 143 is connected at its lower end tothe rod or core 126 of the cornshocker. This rod or core lis provided,near its upper end, with a collar 127, which is adapted to engage andrest upon the upper end of the sleeve or shell 128, in which the rod orcore 126 is fitted. Both the shell and core are round in cross-section,and the collar 127 is formed with notches 129 on its opposite sides, inwhich the levers 130 are fulcrumed, by means of the pins 131, which passthrough the eyes 132 of the lever and into the collar. The lower arms ofthe levers 130 are formed with the inwardly-extending lugs 133 to enterthe notches 134 in opposite sides of the shell, whereby the collar 127is held in contact with the upper end of the shell 128. Fixed to theupper part of core 126 are the opposite studs 135, provided with theslots 136, for the reception of the opposite arms of the levers 130,spiral springs 137 being arranged around the studs togive the upper armsof the levers 130 a tendency outward, thus normally holding the studs133 in engagement with the shell 128. The upper end of each of thelevers 130 is formed with an inwardly-inclined portion 138, to engagethe inner' face of the hollow contracting cone 139, which is rigidlysecured to the outer end of the jib, by means of the arms 140; said armsbeing secured to the jib by the bolts 141, and to the opposite sides ofthe cone by rivets. The cone 139 is thereby held a slight distance belowthe plane of the jib, and is formed with the open upper end 142, whichis located directly under the drum 112. The rope or cable 143 isconnected to the drum 112, and thence proceeds down through the open end142 of the cone 139; around the pulley 144 on the core 126; up and overthe pulley 145 on the outer end of the jibv; and finally down to theupper cud of core 126, to which it is secured. As the drum 112 revolves,and the cable 143 is wound thereon, the core 126 and shell 128, and theattached parts are elevated, and when the ends 138 of the levers engagethe cone 139 they are contracted, thereby disengaging the lugs 133 fromthe notches 134, and releasing the shell 128.

Pivotally connected to and depending from the lower end of the core 126,are the lrods 144, which are pivotally connected at their lower ends tothe inner ends of the guide-levers 145. These levers are pivoted in theupper ends of the vertically-elongated slots 146, of the shell 128, sothat they will be capable of swinging downwardly, and into the slots,when the core 126 and attached rods 144 are raised. This constructionalso allows the guide-levers to swing out horizontally when the core 126is IOO IIO

moved downwardly, since the rods 144 will The rods 144 and guide-levers145 are the means of connecting the core 126 and shell 128, and ofpreventing excessive independent movement, and these parts are'sorelated to the llevers 130 that they will not allow the shell 128 enoughvertical movement to cause its upper edge to move below the lugs 133,though they will allow the shell to move so as to place the lugsdirectly adjacent to such edge. Formed in the lower end of the shell128, and extending upwardly therein, is the square opening 147, which isadapted to receive the vertically-extending standard 148 of the table67. The standard 148 is mounted on the table by means of the upwardly-extending lugs 149, which are rigidly secured to the center of the tableand provided with the stout pin 150, which passes through the two andthrough the standard'148. By these means the shell and core aresupported, when not suspended by the cable 143, and owing to the form ofthe opening 147 and the standard 148 the shell Aand core are made torevolve with the table. Fixed to the mast 99 at a point just above thebeam 8 is the forwardlyextending arm 151, which is provided with the'cord 152, passed forwardly to the vicinity of the seat 10, so that itmay be reached by the driver. By drawing the cord 152, the arm 151, andconsequently the mast, may be turned 'or revolved on its mountings, soas to f throw the jib from over Ythe table 67 to the rear of themachine, as will be more fully described hereinafter.

153 indicates two pairs of shafts by which the drawing of the machine iseffected, and these are arranged so as to allow one row of corn to passbetween them, and one on each outer side, a horse being hitched to eachpair of shafts. The machine is adapted to cut three rows of corn, and toeffect this it will be necessary to have the horses pass one in eachrow. This may be done by means of the shafts 153, one pair for eachhorse, or by means of the tongues 154, of Fig. 8. The tongues and shaftsare connected to the bar 18 by the usual thill-coupling, and will bewell understood.

By reference to the drawings the operation and use of my invention maybe traced as follows: The team of horses for drawing the appliance ishitched to the shafts 153, and the machine drawn through the field,longitudinally with the rows of corn, and with three rows in the path ofthecutting apparatus. As the cutting mechanism operates to sever thestalks, the arms of the reel simultan eously operate to throw the cornof the outside rows back upon the carrier-chains 44, while the middlerow of corn is forced rearwardly between the shafts 36 and 37. Thus thecorn is carried from the outer ends of the cutting apparatus to themiddle thereof, and through the space between the shafts 36 and 37,where it meets the stalks of the inner rows and is carried therewithinto the space between the arms 93 of the standards 90. When the cornattendant turns the standards, so that he may readily grasp the corn,and so that the next e arm of the series 93 will be in position to catchthe incoming corn as before. After the attendant grasps the bundle ofcorn it should be lifted upon the table 67, and deposited between two ofthe guiding-levers 145, and resting upon the surface of the table. Thisoperation should be continued until the spaces between the leversdirectly adjacent to the attendant are filled, whereupon the lever 84 isswung on its fulcrum so as to engage the beveled gears 78 and 49, thuscausing the shaft 75 to revolve, and with it the table 67. In this waythe table is turned through a partialy revolution to place the remaininglevers 130 adjacent to the attendant and in position to be filled withthe corn from the standards 90. Thus itvwill be seen that the corn isplaced around the sleeve 128, and held from falling off by the levers145, and when sufficient corn has been collected to form a shock, theattendant should bind it securely with rope or wire, as preferred, carebeing taken to get the binding above the levers 145. The driver thenmoves the lever 121 to the right, and thereby turns the rock-shaft 116and moves the rod 115 longitudinally to engage the drum 112 with theclutch-member 114. This will wind the cable143 upon the drum and operateto raise the core 126, shell 128, and the entire shock of corn, which,as before explained, is bound thereto. As soonas the upper ends of arms130 engage the inclined faces of the cone 139 they will be forcedinwardly, thus disengaging the lugs from the notches 134, and releasingthe shell 128, when the shell and the shock will drop. ,As the shell 128moves on the core 126, the rods 144 will cause the guide-levers 145 toswing on their fulcrums and throw their outer ends downwardly, therebyreleasing the shock and allowing it to drop to the ground. Thisoperation must be preceded, however, by swinging the shock rearwardly inorder to clear the machine, and to effect this, the cord 152 is graspedby the driver, prior to the engagement of levers 130 with the corn, anddrawn toward him,which will throw the arm 151, and consequently the mast99 and all of its attachments, to the left, and place the jib 108pointing a quarter rearwardly. The operation of the parts must be sotimed that the levers 130 will engage the cone 139 immediately after thejib has assumed this position, so that there will be no delay, and toeffect this the drum 112 and arm 151 should be operated simultaneously.When the shock has been dropped the arm 151 should be swung to theright, which will cause the mast to return toits normal position,whereupon the attendant should lift the shell 128 and place it upon thestandard 148.

IOO

IIO

It will be obvious that the drum 112 should be disengaged from theclutch immediately a supporting framework, cutting mechanism,

upon the engagement of levers 130 with the cone 139, to avoid injury tothe machine.

It will be understood that the hollow shaft 101 and the parts gearedthereto, will be revolving continuously during the progressive movementof the machine, and that this will not be affected by the swinging ofthe mast when operating to deposit the shock.

Having described my invention, what I claim is 1. In a corn harvester,the combination with a supporting framework, cutting mechanism, andmeans for operating the same, of a shockform having a shell, a coreslidably fitted in the shell, stalk-holding levers fulcrumed upon theshell in longitudinal slots formed therein and connected to the coreinside of their pivots, locking devices for securing the core and shellin their normal positions, elevating,r mechanism, and means fordisengaging said locking devices, whereby, when the locking devices aredisengaged, the stalk-holding levers are folded by the downward movementof the shell, and said downward movement is limited by the connectionsbetween the core and the stalk-holding levers to prevent separation ofthe shell from the core, substantially as specified.

2.
